Terrorism Blocklist

This list is compiled by the Counter Terrorism Internet Referral Unit (CTIRU), who sit within the Metropolitan Police Service, and contains URL links to online terrorist content. Receiving the URL list through a filtering provider will mean that your organisation will be able to block this content.

What does the guidance say?

The Prevent Duty Guidance specifies that:

  • Schools in England and Wales are "expected to ensure children are safe from terrorist and extremist material when accessing the internet in school, including by establishing appropriate levels of filtering"
  • Local authorities in Scotland should "have policies relating to the use of IT in schools" and "consideration should be given to the use of filters as part of the strategy to prevent people from being drawn into terrorism"

Further guidance on appropriate filtering can be found on the UK Safer Internet Centre website.

Appropriate Filtering Guidance for Schools

The list is not blocked, what do I do?

For schools in England and Wales using a UK Safer Internet Centre approved filtering system, the terrorism list should be automatically applied and you should not be able to switch it off. If the test is showing that this content is accessible, then you should check with your IT team and filter provider to determine where this issue is. The problem may be limited to the device you tested on or there may be a wider issue.

If your filtering provider does not filter this list and you want to benefit from it, please inform them that you wish to receive the CTIRU filter list. Your filtering provider should contact CTIRU to arrange access to the list.

If you do not have a filtering provider or do not know whether you have a filtering provider, you can contact any of the providers listed on the page below to put in place appropriate filtering for your organisation. To benefit from the CTIRU filtering list, please inform them that you wish to receive a solution that incorporates CTIRU filter list.
